Hi,
Reversing polarity for a motor reverses direction, so does switching the wires on the motor controller do the same?
May sound stupid, but I just want to make sure switching the connection from the motor to controller will not hurt the controller.
Switching the motor leads reverse the motor’s rotation, and won’t do anything harmful to the controller (unless you happen to swap a motor lead with a power wire).
You could also reverse direction with software. Make your speed a negative number and the motor will spin in reverse.
